It seems to be exactly like that.


I have now provided a simple Dockerfile 
to setup standalone NETCONF get-config script using
FoD/ncclient library to hide all the init steps necessary.

On the newest commit of branch testing/freertr1 in FoD github repo:
https://github.com/GEANT/FOD/blob/testing/freertr1/Dockerfiles.d/Dockerfile.fod_netconf_get

To use it, just run (from top level dir of the checkout):

docker build -f vnet_router/rtr/Dockerfile.fod_netconf_get -t netconfget1 . 
docker run -ti -e=NETCONF_HOST=10.10.10.10 -e NETCONF_PORT=830 -e NETCONF_USER=netconf -e NETCONF_PASS=netconf netconfget1
# replace values of NETCONF_* as appropriate

So, can easily test the strange behavior of ncclient yourself.

Best Regards
David
